amazing sound, thats the main benefit. the usual "complains" about spending money for an exhaust with no power increase makes no sense to me. there are tons of mods which add no power, and people do them anyways for several other reasons. enjoyment goes far beyond more HP.

Hey there, folks. Just going to weigh in here.
I've driven two press cars for a week at a clip and now have my M2 with the MPE. In my opinion, it's worth every dime and I wouldn't look back. It really makes the M2 come alive and, frankly, I think it sounds way better and more Porsche-like. Stock exhaust is way too quiet, IMHO. |

Having had both the stock exhaust and now the MPE, its no contest! MPE is awesome!
It may not add any power, but it certainly adds a massive smile to my face! Well worth the cost, I looked at the Akra, but at nearly £6k with the cat, it was just too much money! Buy the MPE, you wont regret it! |

The box?
Where do you unplug the box? Do you mean back at the the muffler?

I have a question about the MPE that those of you who've tried both stock and MPE might be able to answer...
The stock exhaust, as I understand it, has valves in it that open and close based on engine temperature, engine revs, and drive mode. The MPE has a bluetooth remote which has a track option? Why doesn't the MPE just operate like the stock exhaust, or does it also do that? Does the car control the MPE automatically as well as the bluetooth remote?

The bluetooth button allows you to override the the stock control of the exhaust, so that it's permanently open? I'm surprised no-one has been able to code the stock exhaust to be open all the time if that is the case... but if I'm understanding you correctly, I get what you're saying - if the car doesn't have a button to permanently activate the stock exhaust valve to open, there isn't one after the MPE is fitted either... hence the bluetooth one. Can anyone confirm that my understanding is correct? Are there two valves in the stock, and two in the MPE, just controlling the outer or inner pair of pipes?

The valve in the exhaust is purely Bluetooth control. It cannot be opened by the car's software because opening the valve raises the car's decibel level above that of which is legally allowable by European law, at least bmw can't legally code that. The difference in burbles are all from the ECU software for each mode. Opening the valve just makes it much much louder and deeper.

The valves are so far back in the system you can actually see them from standing behind the car.

That does make sense, but if there are valves in the stock exhaust... what do they do?

European sound regulations are quite strict compared to ours. On top of that BMW makes polished quality "luxury" (sadly) cars. So they have valved exhausts, ever since they added a butterfly valve in the e46, to make idle quieter but also have the ability to open under load for aggressive tone.

I admittedly have not tried the 'Performance' exhaust. However, I have a Dinan exhaust on my E36 M3 and have always loved the way it sounds. To my ears, the stock M2 exhaust is more aggressive than my Dinan when the car is in sport mode. Why anyone would find a 'louder' exhaust a necessary or desirable modification is absolutely beyond me.
I live in a small town outside of Seattle and thus far seem to have the only M2 here. People walk up to my car on a regular basis to tell me (1) the LBB metallic paint is the most striking, beautiful color they have ever seen on a car; and (2) they love the throaty exhaust, complete with crackles and pops when I ease off the throttle. The folks at the local grocery have told me they know when I'm pulling into their parking area - they recognize and hear the sound of the exhaust from inside the store. My wife knows when I'm driving up the main street in town because she can hear the car coming from her office nearby. Unless you feel the need to annoy your neighbors or to be confused with an oncoming fleet of Harleys or hopped up rice rockets, I cannot possibly see the need for a 'performance exhaust' that adds exactly zero to the performance of the car and merely makes more noise. BMW got the M2 exhaust right, unlike the M3/M4, which both sound like vacuum cleaners, not like gasoline powered automobiles, much less BMW M automobiles. |

After you press the Bluetooth button and the valves open, open the trunk and lift up the panel where the battery is. The controller box has a plug in the top which once unplugged will leave the valves open until you plug it back in.

I assume you meant ASD? You can get rid of the those fake sounds by either bypass harness or coding (eg. BimmerCode)
You can have some read here - http://f87.bimmerpost.com/forums/sho...&highlight=asd Cheers. |
